You did locate the wheel correctly?From memory the 5 spokes have a series on holes where the 4 retaining pins from the hub locate, you can get the pins in between the holes on the wheel if you're not looking.I did this once and couldn't for the life of me figure out why I couldn't tighten the wheel up it took quite a bit of checking here and there until I'd discovered I have "wedged" the pins between the associated holes (probably not a good description) removed the wheel and reseating in the correct position and everything lined up as it should
